My system:
AMD Athlon 64 X2 4400+ (2.3ghz)
80gb HD
NVidia 6150 Onboard Graphics (512 ram)
3gb Ddr2 Ram
Windows XP SP3

That's it.

I am fairly sure I'd need to upgrade my graphics card. Any thoughts?

Would love some talk. I can currently play EQ2 with modifications to the options - like decreasing pixel shading and increasing pixel size (like viewing in lower resolution). I know that even a 8400 GS nvidia card makes a dramatic difference. But it burned.

I really like what I see with Xyson. Nice sandbox feel. But I really hope it stays away from pvp and combat or at least remains cautious. Many sandbox games get ruined by those things because of people dying and griefing and penalties being thrown on them. I really really think the building and exploration elements should be focused on. I also think that a animal population is smart too as long as it's not too aggressive (unless attacked!!).
